Listing is for one new OEM 12-pin harness connector. Connector comes fully assembled with wires pre-installed. This connectors fits dozens of sensors, each with its own pin configuration. Unneeded wires can be removed easily, by pulling them out from the rear of the connector with needle nose pliers. Pigtail wires can not be replaced after removal, so double check which wires need pulling. Please use compatibility tool to verify filament prior to ordering. If your vehicle does not appear on the list, but you believe this is a match to your sensor, please contact me prior to ordering so I may verify filament for you. Connector that have been modified, or attempted to install into a sensor that they didn't fit will no longer qualify for returns.
